Compress images

Make photos smaller for email and uploads, without a visible quality drop.

Processed in your browser. Nothing is uploaded.

75%

Higher keeps more detail and makes a bigger file.

Optional. Resizing is usually the biggest single saving.

How to compress images

  1. 1

    Add your images. Drop photos onto the box above, or click to browse.

  2. 2

    Choose how hard to compress. Lower the quality slider, and optionally cap the longest side, until the size suits you.

  3. 3

    Download. Each result shows its old and new size. Save one, or all as a zip.

What actually makes an image smaller

Two things, in this order. First, dimensions: a 4000-pixel-wide photo shown in a 1200- pixel-wide slot is carrying nine times more pixels than anyone will see. Capping the longest side is almost always the larger saving. Second, quality: JPG and WebP discard detail the eye is bad at noticing, and how much they discard is the slider.

Around 75% quality is the point where most photographs stop looking any better to a human but keep getting bigger on disk. Start there and only raise it if you can see a difference in the file you actually care about.

Why this one does not upload

The images people compress are the ones about to be attached to something: an insurance claim, a rental application, a passport scan for a visa form. Those are exactly the files that should not be handed to a stranger’s server to save a few hundred kilobytes. QuietFiles compresses them in this tab and never transmits them.

Questions

How much smaller will my images get?

A typical phone photo drops by 60–85% at the default settings, and much more if you also cap the longest side. Every result shows the before size, the after size, and the percentage saved, so you can judge it per file.

Will the photo look worse?

At the default quality, not noticeably on a screen. Compression discards fine detail first, so the difference shows up when you zoom in or print large. Raise the slider if either of those matters.

Can I compress an image to a specific size, like under 2 MB?

Not automatically, but the results list shows each output size immediately — lower the quality slider a step and convert again until it fits. Capping the longest side gets you there much faster than quality alone.

Does compressing remove EXIF and GPS data?

Yes. The image is re-encoded from decoded pixels, so camera details and location data in the original are not carried into the output.

Are my photos uploaded to compress them?

No. Nothing is uploaded. Compression uses your browser’s own image encoder, running on your device, and the page cannot send your files anywhere.
